title: Porphyria cutanea tarda with constrictive pericarditis in a family.
abstract: Two cases of familial porphyria cutanea tarda (PCT) with constrictive pericarditis are described. A 50-year-old woman and her 48-year-old younger brother were admitted because of right ventricular heart failure. Constrictive pericarditis was diagnosed by RV pressure waveform and echocardiogram. The patients were diagnosed as PCT based on clinical symptoms, histologic findings and elevated urinary excretion levels of uroporphyrin. Even to this day, over 40% of the etiology of constrictive pericarditis remains unknown. There is a possibility of overlooking porphyria cutanea tarda in constrictive pericarditis patients. This report describes the first documented cases of familial PCT with constrictive pericarditis.
